Valentino Rossi: The Doctor Series Episode 4/5

What makes Rossi, Rossi?

That's the theme in the latest episode of Valentino Rossi: The Doctor, in which the crew takes a closer look at the man behind the larger-than-life persona, a man who has somehow continued to keep the same drive as he had when he came into the sport.
